Possible Causes

Weak heating element, Damaged or compressed door gasket, Poor insulation in cabinet, Misreading temperature sensor

How to Fix / Troubleshooting

Safety first: Unplug and cool the smoker before inspecting seals or internal parts.

  • Door seal test: Look for smoke or heat escaping around the door during operation. Inspect the gasket for cracks or flat spots and replace if necessary.
  • Check for cabinet damage: Dents or gaps in the cabinet can reduce insulation effectiveness. Seal minor gaps with high-temperature silicone where appropriate.
  • Compare temperatures: Place an oven thermometer inside and compare to the display. If the smoker reads higher than actual, the sensor may be faulty and should be replaced.
  • Element performance: If preheat times are very long and the element does not glow strongly at high settings, replace the heating element.
